**Target albedo = 0.3 @ 1,570nm.
Sealing
- Hermetic
Laser Safety
- Class 1M ***
***AS/NZS IEC60825. 2011.
Transmitter
Laser type | diode pumped Nd:YAG/OPO |
Wavelength | 1,570 nm |
Output | nominally 8mJĀ [to Class 1M limit] |
Ranging rate | 10Hz typical, up to 20Hz (with duty cycle) |
Detector
- InGaAs with time variant gain
Range Determination
- Signals from the detector are digitally sampled and examined to determine all potential real target returns. An adaptive range threshold compensates for changing noise levels, maximising system capability under varying conditions.

- 12 to 32Vdc input
Comms
- RS-422 19,200 Baud
Mounting
- V-block type
